We have heard of the claims about fibre from shell fish being used in this way and this innovative supplement has certainly got us interested. We look into B-Slenda to find out more.
B-Slenda is designed to reduce your calorie intake by binding with some of the dietary fats that you eat in order to make them pass through the body rather than adding to your weight. This innovative new diet supplement is based on a fibre containing shellfish so will not suit you if you have an allergy to seafood.
B-Slenda is manufactured by International pharmaceutical and supplements company Pharma Nord who have their corporate headquarters based in Denmark. The company sell mainly throughout Europe and the UK and the British head office is based in Morpeth in Northumberland.
All Pharma Nord supplements are manufactured in Denmark and comply with high standards of production safety in accordance with the current Good Manufacturing Practice (GMP) and Hazard Analysis and Critical Control Points (HACCP) guidelines.
Pharma Nord products are on sale in over 45 countries and include vitamin supplements for a range of conditions including weight loss, bones and joint care, eye-care and much more. The product range is huge and includes Flaxseed oil for bone protection, statiquinon a colestertol reducing supplement, Bio trim a weight loss supplement based on chromium.
B-Slenda is a fat binder and contains FibrePrecise as its active ingredient. This branded formula is made from an indigestible fibre derived from shrimp.
Fat binders work by reducing fat absorption. The fibres create a viscous gel in your stomach which attaches to fat molecules that have not been digested. This creates a mass which is too large to be absorbed by your body and instead passes through your system and is excreted in the normal way.
Fat binders can be effective for weight loss because they do not only reduce the dietary fat intake but also create feelings of fullness in the stomach. The bulk of the fat binder stays in the stomach making you feel fuller for longer. In terms of how quickly they can work is debatable (see our Do the calories really stack up article).
Fat binders often contain vegetable fibre as the active ingredient so B-Slenda is an unusual in the fact that it doesn’t appear to, however the ingredients are a matter for concern.
To use B-Slenda, for weight loss, you are advised to take 2-3 tablets with a large glass of water 30 minutes before two out of three meals.
If you just want to maintain your weight you should take 2-3 tablets before one out of your three main meals. For most people this will be before your evening meal or before dining out or celebratory meals that may be high in fat.
The major drawback is that the company do not provide an ingredients list or an adequate ingredient profile. The company state that Fibre Precise is the active ingredient but that is as far as the ingredients information goes.
There is no ingredients list and no amount quantities provided by Pharma Nord in the advertising.
According to the Slenda advertising the raw material (the shrimp) is fully traceable all the way back to the actual fishing vessel that caught the shrimp for each batch of product.
That’s all well and good but for the customer a meaningless claim. While we are all in favour of transparency throughout the manufacturing process, we would have prefeered to have seen a simple ingredients list that would have helped customers know exactly what they are buying.
According to the advertising Slenda B is a second generation fibre that binds only fat and not sugar , carbohydrate or alcohol. You are advised to cut down on these foodstuffs because they are also fattening.
The product information states that each B-Slenda tablet can bind “up to 20g” and consequently prevent “up to 180 calories of fat”. Note that this is “up to” and the real effects may not be as effective as these figures.
If you eat a fatty meal during this period, the fat molecules will attach to the fibres in FibrePrecise instead of being absorbed in the body.
You are advised to use B-Slenda before you eat high fat foodstuffs such as:
The fibre and fat is then excreted without any unpleasant side effects.
B-Slenda contains a branded formula FibrePrecise as its sole active ingredients (see more information here). This supplement is registered as a;
a class III medical device that has been certified for use as part of a weight management programme.
A medical device in instrument that does not achieve its purpose by chemical reaction in the body – which would make it a drug.
A “medical device” does not have to conform to foodstuffs standards and unlike products described as drugs or foodstuffs, does not have to provide any proof that it is safe or even works.
Even the ingredients do not have to be outlined. A certified medical device can be loophole that enables the manufacturers to sell products without an adequate ingredient profile or any benefit to the end user.
We covered medical devices in an early investigation on should over the counter diet pills be more regulated.
Although a medical device classification makes a product sound official and proven to work, the truth is not as rosy.
A Class III device is one for which insufficient information exists to assure safety and effectiveness solely through the general or special controls sufficient for Class I or Class II devices

FibrePrecise is made of icelandic deep-sea shrimp and generally this ingredient is known as Chitosan (read our Chitosan ingredient article for more information).
Chitosan is extracted from the shells and expskeletons of shrimp, lobster and crabs and is a fibrous material. It is believed to block the absorption of dietary fat and research is ongoing. However, results have not been conclusive and there is a lack of evidence that shows it works to block dietary fats.
There is conflicting evidence too. Some clinical evidence has suggested that it simply does not work in the way as described and did not perform better than a placebo. One randomized, double blind trial of chitosan for body weight reduction found that:
chitosan in the administered dosage, without dietary alterations, does not reduce body weight in overweight subjects.
We feel that Pharma Nord have taken advantage of the medical device classification in not providing an adequate ingredients profile for this supplement.
Yes, the product advertising explains how this supplement is supposed to work but it does not provide any real hard facts about what is actually contained in each tablet, and it does not cite any clinical evidence that suggests that it will work in the way as described. The fact that clinical evidence is disputed means that your weight loss effects are not guaranteed.
If Chitosan is the sole ingredient contained in Slenda B, this supplement should be safe for most people, The big problem is that we do not really know what is in it and there may be added ingredients that do not suit everyone.
The fibre (Chitosan) may cause increased bowel movements or diarrhoea, increased flatulence or mild stomach pains.
Caution: Avoid if pregnant or breast-feeding. Do not take B-Slenda if you have an allergy to seafood. Although seafood allergies are often caused by the meat and not the shell, it is best to stay on the safe side,
Do not take B-Slenda if you are taking Warfarin or it could interact with medication.
We could only find a couple of independent customer reviews for B-Slenda.
One customer was not impressed.
I only took the one course ….and because I noticed no change I decided to try self control and save my finances!
However the other reviewer has lost some weight;
I started taking B-Slenda on the same time I modified my eating habits, so I am not sure if I am losing weight because of the diet or the product.
B-Slenda may help you if you change your dietary habits but we are not convinced. In addition if this supplement really does work you are committed to taking this supplement forever unless you change your eating habits.
Fat is fattening and simply taking a supplement to remove via the toilet, what you have already eaten is not a healthy option.
You can buy B-Slenda via the product website.
Each pack contains 40 capsules and costs £13.30 and will last between 1 and 2 weeks.
If you take B-Slenda to lose weight at the recommended dose of 6 tablets a day, the packet of 40 will only last for a week!
However if you are taking B-Slenda to maintain your weight and sticking to the lower dose of 3 tablets a day each packet will last around 2 weeks.
Price includes free postage to UK and Europe. International worldwide postage costs a flat rate £5.95 to addresses outside the EU
B-Slenda is also available via other online retailers including Amazon. A 40 tablet pack of B-Slenda costs £16.99 via Amazon .co.uk and includes free shipping. B-Slenda is also available direct to US customers via amazon.com.for $30.00 plus $7.00 shipping.
No money-back guarantee is on offer.
We are not impressed with B-Slenda. Although Pharma Nord is a well-known and reputable company who sell a range of good quality health supplements, we don’t feel that B-Slenda is a good product.
There is a real lack of ingredients information, plus inconclusive evidence about the weight loss effects of the active ingredient. In addition this supplement is expensive if you take it for longer than a week.
The idea that you can eat what you want and then expect to remove the evidence by taking a supplement is not a healthy habit to get into. And even if B-Slenda does work in the way as described, it will not help you change your relationship with food and avoid putting weight on in the future.
We have no other choice but to reject B-Slenda.
